motor prob (overheating) - 11-30-2005, 12:37 AM
ok as some of you may know i have been having a prob with my motor overheating. Well i took the motor apart today to look at the p/s and first off the pistons black as night! (figured that though, motors hit 400 a couple of times) first time it was a cut fuel line, second/third/fourth time no clue? well i pulled it apart and noticed the backplate was really lose and i was missing a screw. could this have caused a big enough airleak to throw my tune way off and cause the motor to go WAY lean! any help would be appreciated! thanks in advance!


btw i already know i can't tune so leave that hint out!

Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. Though wise men at their end know dark is right, Because their words had forked no lightning they Do not go gentle into that good night. Good men, the last wave by, crying how bright Their frail deeds might have danced in a green bay, Rage, rage against the dying of the light.

Any air leak will cause tuning problems seal it up with some RTV or that Racer's Edge stuff.

If only I were a millionare.

many times the top of the piston gets black from running rich check to see if it is burnt alum or just burnt fuel residue

Like Rich said any airleak will cause problems. Goto the hobby shop and pick up some carb seal or somethin liek rich said and seal Everything. Carb backplate, a little around the HSN and the carb bolt. none on the head. Tighten everyhting up, and clean it (clean motors are happy motors) Then go out and run it over. If you have to cgo back to factory settings and go from there. If you still cant get a tune/idle or anything check ur clutch setup.
