1999 Indy 500 . Carbs cleaned and tuned. Occasionally have to get off sled and help it out by giving it a push or lifting off ground hammer it and jump on fast. Runs great other than that . Any ideas?

RJ Gleason

New plugs?

Sounds like a belt issue! Clean the sheves and start with a new belt! Get your center to centers right!

Do you notice a difference if it is hot (hot as in you are going through deep snow or working it really really hard) or does it normal driving.

What RPM does the clutch engage at?

No really just gettin going . For example on ice the other day I just put feet on ice and opened up then jumped on. Need to drive hard ! Did notice plug cap was loose on wire and retightened. Possibly it?

Not sure about rpm

meburdick

If you're engaging below 4000, the spring in your primary could be worn. If you're engaging below 3000, the spring could be broken.

You could also have poor adjustment of the secondary, a worn belt, or even the wrong belt.

Start your sled up in the dark and look around the plug caps to see if they are arcing to the head. If it has choke pucks on it make sure you have them adjusted with the proper play and they are sliding freely.
