Need to replace my engine

[Bee Bop]

I have a 1999 ez go gas with a Robbins motor. I just got it a few month ago and it has been running fine. The starter went out so we pulled the engine to replace the starter. When we had it out we decided to replace all the seals/gaskets. We couldn't get the clutch drive assembly off, tried for two days (using an impact driver and various methods,also the correct tool) and no luck. I said **** it, and we put it back together. It then would start and drive at low RPM, but when you gave it too much gas it bogged down. I gave up and took it to a repair shop. They told me the compression was at 90 and had to be a minimum of 120. The robbins engine is discontinued, so I don't want to rebuild. What is the most inexpensive route for replacing the engine?...maybe a honda...but I don't want to lift it or pay $1200 for a plug and play mounting kit, plus cost of the engine....any suggestions?

I completely understand your frustration with the situation. Replacing the starter and dealing with the clutch drive assembly can be a real headache, especially when it feels like you're getting nowhere. However, in your case, rebuilding the existing Robin engine might actually be the best route to take. Here’s why.

Firstly, while it’s true that the Robins engine has been discontinued, parts are available, and a rebuild can restore it to a state that's almost as good as new. The key here is finding a reputable repair shop. The compression issue, with your engine currently at 90 PSI and needing more is typically a sign of worn piston rings, valves/seals, or cylinder walls. These are all issues that can be addressed effectively during a rebuild.

You mentioned the repair shop suggesting that the engine is not viable due to the low compression. However, it’s worth considering that some shops may not have the expertise or willingness to undertake a rebuild, which can be time consuming and require specific skills. It's possible they recommended against it because they prefer to handle easier or more profitable jobs. A second opinion from a shop that has experience with older golf cart engines could provide you with a clearer picture and a more cost effective solution.

On the other hand, attempting to replace the engine with a different model, such as a Honda, brings its own set of challenges. There is no true plug and play replacement for the Robin engine. Custom fitting a new engine involves significant modifications. You’ll likely face issues such as fabricating new engine mounts, aligning the clutch and drive systems, adjusting the throttle linkages, and possibly rewiring parts of the electrical system. These hidden issues can add up quickly, both in terms of cost and time, and may lead to a less reliable setup if not done perfectly.

Despite the initial concerns, rebuilding your existing engine is likely the most practical and economical solution. It avoids custom fitting a different engine potentially saving you a lot of hassle and expense in the long run.
