Mike Etheridge 1 Posted October 28, 2018 Share Posted October 28, 2018 I have had plenty of experience with starting diesels in the past but not twins . As a guess I would slacken off the compression on both cylinders so that neither would fire. Assuming the engine would start on one cylinder I would then increase the compression on one cylinder and go through the usual procedure of starting by flipping over the prop with a large propeller fitted. Once started on one cylinder, I would then gradually increase the compression on the other cylinder until it also fired. Then I would adjust the needle valve for optimum performance and slacken off the compression on both cylinders as necessary as the engine warms up. Anyone agree ?

Don Fry Posted October 28, 2018 Share Posted October 28, 2018 My dad used to have a marine one in an Aerokits Alco Torpedo boat. It was a very nice motor to use. From memory Mike is about on the money. But it wasn't difficult, as I would have set it up, and I would have been about 12 then. Dad was better on steam engines Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted October 28, 2018 Share Posted October 28, 2018 Mike is pretty much on the money if the settings have been lost. The Taplin Twins came in a box that had a large label fixed across the engine ,that had to be torn away to get the engine out . It read " PLEASE READ INSTRUCTIONS BEFORE CHANGING ANY OF THE SETTING" or words to that effect. The engines were factory set to start but obviously had to be run in and settings adjusted. To start diesels you need "The Knack" and an ear for an engine that only comes with experience . Anyone who has played with them will know what I mean . Starters are taboo and can destroy a model diesel in seconds They were /are nice engines if you belong to the " Order of the Oily Hand Society " and like diesels . Collectors love them and I'll be very interested to see what the final price is . I put a old water cooled Taplin Mk1 with green heads that run but needed attention on Ebay a few years ago and that made over £200 much to my surprise.back in the 1950's run Model boats at Clapham Common with very primitive carrier wave Radio Control . the RXwasa valve set made from plans in the RCM&E by a friends dad. I couldnt afford a Taplin but managed to get a marine ED Hunter (half a Taplin Twin) as the early cylinders were made for Taplin by ED Great engine Quote Link to comment Share on other sites More sharing options...

John Duncker Posted October 28, 2018 Share Posted October 28, 2018 Total pussy cat to hand start although a leather glove is always a wise precaution. Quote Link to comment Share on other sites More sharing options...
PatMc Posted October 28, 2018 Share Posted October 28, 2018 They're dead easy to start. Pity about the weight & lack of power. Best suited to a model boat or steam roller. Quote Link to comment Share on other sites More sharing options...
Don Fry Posted October 28, 2018 Share Posted October 28, 2018 Yea, for that money you can get a modern motor. And I bet a hundred hours of use and while a modern motor is still considered new, the Taplin would be tired. But back then, the Taplin at least started, and ran, idled and went vrooom. Which was a country mile better than a lot of the scrap we were sold. Quote Link to comment Share on other sites More sharing options...
PatMc Posted October 28, 2018 Share Posted October 28, 2018 A contemporary Merco 49 was 35% lighter similar capacity with 30% more power. It was no ball of fire but much more practical for a model plane. Quote Link to comment Share on other sites More sharing options...

Don Fry Posted October 28, 2018 Share Posted October 28, 2018 But in all fairness Ken, and you might be right, I even serpent ( read suspect) you would fail if you bid, it's going for more than that . But will you be bidding? I'm out, buy a Laser, OS, Saito me. I wish the inventor of spellcheckers a hot corner in hell, without a dictionary.

Martin Dance 1 Posted October 28, 2018 Share Posted October 28, 2018 Well the Taplin Twin went for £483. A motor that was built some time in the 1960's has never run and will almost certainly never be run. It will likely just become an ornament. I have several MDS motors which can be used as ornaments for much less than £483 Now where's that thread about when does a model become too expensive?

Peter Miller Posted October 28, 2018 Share Posted October 28, 2018 I flew a Taplin Twin in a Powerhouse. Flew it quite well in calm conditions. Started easily on one pot and then bring the second one in. (I later fitted a Merco 61. (Not a tremendous change in performance) No gloves or anything, just a normal hand start But then we started everything by hand many years ago normally with bare fingers too, you just had to develop the really fast flick. All the bad accidents happened once the engine was running. I used to hand start a Super Tigre G21/29 speed engine running on 20% nitro and a 7X10 (7" diameter) wood prop and it never bit me. As I say, you developed a really fast flick! Edited By Peter Miller on 28/10/2018 18:21:44 Quote Link to comment Share on other sites More sharing options...

brokenenglish Posted October 28, 2018 Share Posted October 28, 2018 I disagree with several of the remarks made above. A properly set up Taplin Twin does start in just one flick, every time. It's true that it's a bit heavy of course, but this is OK in a short nosed vintage model, and the TT is an ideal power plant for something like a Radio Queen or a KK Falcon. You can see the one-flick starting in this video. Apologies for the video quality. It was shot in an old format and has been "converted" several times... but the engine is superb. No engine is easier to start than a TT, not even a Mills... **LINK** Quote Link to comment Share on other sites More sharing options...
Don Fry Posted October 28, 2018 Share Posted October 28, 2018 I don't disagree, it a nice motor. But £480 is a serious outlay to steer a KK Falcon round. What do you need, with a modern motor, to do that? Quote Link to comment Share on other sites More sharing options...

But £480 is a serious outlay to steer a KK Falcon round. What do you need, with a modern motor, to do that? Yes Don, but there are still a few people who like to see old timers flying with lovely old vintage engines, and I'm one! I agree about not paying £480 (and a Mk I or II would have been more expensive) just to steer a model around but, I've been collecting and playing with these old engines since they were current, so there aren't many that I don't have, without paying serious money. Another important point, for our "modern" RC flying is that there aren't many real vintage engines that have a throttle. I can only think of the TT (and the RC throttle comes from its boat heritage), plus the Mills 1.3 and Forster 99, both of which had throttles intended for timer operation. OK, there's aftermarket stuff for ED Racers and Hunters, etc. but that doesn't count as old timer! Anyway, the TT is a superb engine. In my earlier post, I shouldn't have used the word "flick" for starting... a gentle shove is all that's required. Quote Link to comment Share on other sites More sharing options...

Tom, I have several TTs, but if I could fly a Mosquito, I'm afraid it would have to be electric! Quote Link to comment Share on other sites More sharing options...
