Olds Hit Miss half scale

[Helder22]

Just testing it prior to disassembly for painting and general smoothing out of cast parts. Still have to make a couple parts like a muffler and fuel tank. Oh, and a base too. Here it is running on camp fuel with 10% WD40.
It's not broken in yet as it only has about 4 or 5 minutes run time on it I guess.

Thanks guys.
I considered leaving it as it is right now but I really wanted to see what it would look like with a nice coat of paint. Working on it right now. Should have some results soon!

Hi Helder, I have an Olds model engine and we are having a hard time getting it started, we did put an electric motor to it and it ran, but seems like its not getting fuel? Thanks Wayne

Lovely smooth and consistent running.
Are you sure you want to dismantle it?

Is it a 1/2 with the big "B" on the side or a 1/4 scale?

 

[Helder22]

Too late Jim, already been dismantled, sanded, epoxied, primed, painted, polished and put together again!
I've tested it and, thank goodness, after a little tuning its running just as it was before.
Now Im just working on the gas tank and then all I have to do is make a nice wooden base for it. Oh and add the muffler.

Lovely smooth and consistent running.
Are you sure you want to dismantle it?

Well done Helder, I look forward to seeing the finished engine.

Whizzerkid,
Do you have your timing right? if you turn the wheel by hand slowly does the spark happen at anywhere between 5 degrees before TDC and TDC? If you remove the muffler on your engine and run it, and you look down the exhaust hole, you should see no red flash/flame in there when there is a "hit". If you do its likely its running too lean. Take a look at my video between 0:58 and 1:06 to see what I mean. When the engine is running, are you getting a good number of misses between every hit (or couple hits)?
Its really hard to diagnose these things without seeing them in person LOL. Maybe if you post a video?

Hi Helder , Engine is in time. Will have to check the firing in the muffler after I take the muffler off. Its cold we have freezing rain so might try next weekend. I know when we had it running we were getting a good number of hits. Also had to put water in the hopper as it was getting very hot! I had a exhaust spring at .047 on it and just got one that is .042 per the print. Thanks Wayne

Hi Herd are you going to Cabin Fever show this weekend? Thanks Wayne
