Bruce Richards Posted June 6, 2010 Share Posted June 6, 2010 For 4 stroke throttles I have used a method of routing the push rod past the throttle horn on the carb then back on its self in a U shape. This only works with a stiff wire push rod but often solves a difficult problem. Quote Link to comment Share on other sites More sharing options...
Phil 9 Posted June 6, 2010 Share Posted June 6, 2010 I find the best way is just to add a snake routed on the left side Quote Link to comment Share on other sites More sharing options...
Doug Ireland Posted June 6, 2010 Share Posted June 6, 2010 Why not try one of those 4-stroke linkages from DuBro? You can get one from SMC for about a fiver and I've used them in the past; very easy to use. Quote Link to comment Share on other sites More sharing options...
Simon B Posted June 6, 2010 Share Posted June 6, 2010 I think you're all over complicating it! I bought a Pulse 40 with an SC52 and then de-slimed it for clean power, but here's how it was mounted with the throttle servo in the cockpit and the control rod running along the top of the nose in a tube.

Bob Cotsford Posted June 6, 2010 Share Posted June 6, 2010 I'll second Bruce's method. When i converted my AcroWot from 2 to 4 stroke, I bent the existing wire throttle pushrod up at 90 degrees to line up with the carb and trimmed it to end about 1/2" below the hole in the throttle arm. Then I fitted the ball half of a ball-link to the carb throttle arm, with the socket part of the ball link pushed over the end of the now vertical pushrod. The ball link can slide up and down on the pushrod to match the radial movement of the carb throttle arm. Quote Link to comment Share on other sites More sharing options...
jonathan wood 1 Posted June 9, 2010 Author Share Posted June 9, 2010 having spent not little a little time squinting somewhat maliciously at the offending throttle connection and bending and rebending my test wire i arrived at what i believe may be a solution. unfortunatly it was at this point that the thread on the carb barrel broke off! i,ve ordered a replacement and if my new system works i will give details of bends and connections for anyone else who may wish to fit an sc 52 type 4 stroke to a pulse 40. thanks simon for the photos of servo relocation, neat idea but definatly more complicated than bendig wire! ( though possibly less time consuming ! ) Quote Link to comment Share on other sites More sharing options...
Simon B Posted June 10, 2010 Share Posted June 10, 2010 See, this is why i love electric. It's sooooo much simpler Quote Link to comment Share on other sites More sharing options...
jonathan wood 1 Posted June 23, 2010 Author Share Posted June 23, 2010 i,ve sorted the throttle and a description of how to install it is on page 2 of my other pulse thread Quote Link to comment Share on other sites More sharing options...
