Hello. I have an old Veco .61 R/C with a pump on the back, attached directly to the engine. All the engine says is: VECO 61. It at one time had an exhaust baffle, but it is gone. There is no muffler. I thought I would post a few questions before running it.
The compression seems low. Is this normal for this engine? Should I try to get the pump working, or is it too old? Do I need to have some kind of back pressure to get the pump to work?It hasn't been run in over 25 years. I have an 11/6 prop. Also a 12/6. Does it matter? Finally, what fuel does it prefer?
Thank you for your time.
Regards,
Frank in Montana
