With the diappearance of the LS Pro 50 twin what other 50 twins are
available on the US market. I liked the LS one because the carb was
underneath the crankcase and therefore easier to make adjustments to.

I plan on putting this engine in a Bud Nosen Mr. Mulligan, projected all
up weight at a max of 20-22 pounds, and hopefully lighter. All suggestions
and discussions are welcome, the reason I want a twin is 2 fold, less vibration
and secondly fitting inside my cowl with no ugly cut outs.

Go to this website.Very nice engine and the weight is very friendly.Then go look at the RCGF thread and see what people are saying.Talk to piston and see if he can give you any info on the 50cc twin.

Another option is a 3w-56. There's also a U.S engine manufacturer making a 48 or something like that but I can't remember their name.

Fox has had a 48 twin listed for years but I have never seen one in person. Don't know if they are still available or not and they were expensive.

DZY had a 48cc but i havent heard anything good here in the forums for a while.As a matter of fact i havent heard anything at all about them.Maybe they gave it up?

The main problem with the DZY is the angle of the plugs. They angle upwards and can be hard to fit in a cowl. The machine work looks good. My friend has one and has not run it yet, so I can't comment on the performance. The Mr. Mulligan has a pretty big cowl so the plug thing might not be a problem.

Plug angle can for sure be an issue when it comes to cowl fit but there's often a "fix" for that. Many engines use a 14mm plug which also requires a tall plug cap. You can install inserts to reduce the plug size to 10mm and use a smaller plug and cap. You might end up changing the compression ratio fractionally but if we're needing every erg of energy an engine can deliver we needed a larger engine anyway.

I was planning a DZY on an RCGuys Ag-Wagon but they seem to have fallen off the face of the planet. Wild Hare was carrying them but have stopped because of no support out of China. I am ordering a RCGF 50 Twin today.

Good idea Pat. Come to think of it, didn't Milton do a thread on this a while back? Here's a link to a thread with pics of the DZY 48. Posts #173 and #175.

I've been doing this on some of my engines for a looong time. My Brison 6.4 and one of my RCGF 100's have been converted to 10mm plugs, and I'm about to convert one of my 50's. You sure don't save any money doing it because you have to change ignitions or plug caps, but it has it's advantages.
