Retrol HM-01 Hit and Miss engine.

This was the first model engine I have built and I’m delighted to say everything went together beautifully. The components are well made and apart from removing a few burrs here and there they all assembled just perfectly. I picked up a few tips from the experts on YouTube along the way and enjoyed the challenge of getting the ignition timing just right. I have found lighter fuel (Shellite in Australia) mixed 40:1 with 2 stroke oil much cleaner burning than petrol and oil mixed at 25:1 as recommended in the instructions. Easier to start as well. I would like to see a battery box supplied with the ignition set and details of the batteries required. Also as others have mentioned, a longer HT lead to the spark plug is needed. Altogether though a beautiful well made engine that I really enjoyed building. Any suggestions what to build next?

As my son was 10 years old and really wanted to build a machine himself, having watched and participated with his father for a long time, I bought the HM 01 kit and let him build the machine according to his own ideas without any help.
Here is the result.

Great little engine. Two minor issues, the spark plug lead is too short for the sled. Yes, it did fit but stretched that made the install wrong and unreliable. I inserted an extension of about 2 niches that fixed the problem. The second issue was the counter-weight flywheel auto centering shim. It did not grip the crank shaft. Again, I needed to add a filling shim to obtain correct grip on the shaft. This is my first model engine, it is great. Runs very nicely and has become a talking piece within the family. I would recommend this little engine, albeit with some minor issues.
regards, Trevor Bright.

High Quality Hit and Miss Model HM-01

I admit, I was a little skeptical at first ! I wondered if the Model I received would look like the one on
The Website ! After talking to a few friends I decided to order one!! I am 100 % glad I did!! These are very well made, highly detailed engines! They were packed very well, arrived safely !!
Probably one of nicest small hit and miss models I have seen for sale online! Mine arrived safely, very well packed! I am looking forward to putting some gas in mine and running it soon! I have received great customer service from this company and would definitely purchase products from them again! I included a picture of mine on the skid before i fastened it or the fuel tank down!

This is a great piece, I have been extremely impressed with all the details. The gas body is super nice the connecting rod details and being cast blew my mind. I can wait yo get everything assembled and have it running. Absolutely no diappointment,
