Re: 1975 Chrysler 10hp 2 stroke refurbish questions

quote RCO:

Sounds to me like it is “four stroking” which is normal when the engine is revved in a no load condition. You really shouldn’t run it much above a fast idle without a load.

I listened to the video several times and didn’t hear anything unusual. But "four stroking" is a definite possibility, which is normal as said. The main thing I heard was my body cringing as I listened to that thing revving so high under no load. Must be a good motor because it didn’t blow up–yet.

I will say one thing, that is a very smooth running motor, practically no vibration.
