"My engine ran great for the four years I've owned it. Only complaint was the throttle would not hold steady rpm's around 4000. Anywhere else it would hold steady rpm's. My mechanic, in whom I have a great deal of confidence, suggested replacing the VRO pump. We did. First time out with the new pump the motor ran great, and even held steady rpm's at 4000 for the first time. After about 30 minutes running time the engine suddenly just died. It re-started easily. It did this twice. Next time out it did the same thing several times, and finally would no longer run as soon as you put it in gear. Did a compression check and there is no compression in the number 3 cylinder. The engine has been torn down and the rings in that cylinder had frozen and there was no lubrication. All other cylinders were fine.

My question is whether this was just an unfortunate coincidence or could it have had something to do with the new VRO pump???"

The VRO pump mixes for all 4 carburetors. That is it is a common supply.So that leaves a plugged carburetor as a possible culprit.When ever a motor is put away for long term storage the carburetors should be drained so that there is no chance for them to gum up.When ever a 2 stroke engine acts up (as in the 4000 rpm bit ) the REAL cause should be determined or problems will result.A compression test should have been done long ago. Just my 2-1/2 cents of advice.
