I have an older r> I just got an ASP 61 in a buy out and was wondering if anyone here has been

Some of these engines are great. Some of these engines are real P.O.S. I have had a couple of each.

We tend to consider them older generation OS but extremely well built and bomb/bullet proof. Once run in very reliable.

powerful motor, the .61 has had three major mods since being available here early 90'3. One problem was that the original "O" rings in the contra needle of a pair of red head ASP .61s circa 1995 did not last long and needed early replacement to prevent them turning out and upsetting low speed and idle [stop the air leaks]. Do not run motor on less than 19% oil and ensure at least 5% castor in the mix e.g. Coolpower Omega. Email for copy of instruction sheet if reqd.

The older ABC version honks and would not be blown away by a Kraft .61, but the HP might give it a good run for its money.

On the older ABC version, stick with props in the range of 11x7 and let it spin.

Eddie..

The ASP's had a large carb bore, as you will notice, and therefore fuel draw was not the strongest around... The stock muffler worked well, but a lot of users went to Pitts style mufflers and could not get the engine to run...

The cause was the large exit area of the aftermarket mufflers. It was necessary to plug off one pipe to get the muffler back pressure to normal..
