Hello all!
I have a GEBE Robin/Subaru 35 cc bike kit installed on my Cannondale mountain bike. The installation went very well, but now as the engine is breaking in, I have a BIG problem. I have slightly over 200 miles on the engine and it is becoming more and more free-revving as it loosens up. In fact, now when I start it, the engine races at an extremely high RPM. This caused me to snap a brand new belt when I tried to put it into gear!
When I started to evaluate what was wrong, I noticed that when the throttle is fully closed, the linkage on the top of the engine is ~5/16" away from the adjustment screw. This screw adjusts the idle speed according to p. 14 of the owner's manual. If the cable were a bit longer I think my problem would be solved. As it is, I cannot slow the engine RPMs down enough.
I have emailed GEBE twice, and just left them a phone message. Hope that they get back to me. If they don't, does anyone have any experience replacing this engine's throttle cable? I checked with a local small engine repair store here and they don't "do" cables.
I have not ridden my little beauty in three weeks now. In fact, I have lost the majority of the summer due to this and another problem on the bike/engine. This is a bit disheartening!
