Default MVVS 6.5 questions

Hi all,

I'm pulling a few of my old glo-powered models out of the attic and checking to see what I can get running.

2 of these have MVVS 6.5cc glo engines, with the 1/4 wave tuned pipe.

One has the plastic arm broken off of the carb, and I think the low-end needle may be slightly bent as it does not rotate smoohtly - has one spot per turn that is tighter.
Are spare parts for the arm & needle (or even whole spare carbs) available at all ? I got these from Morries Hobbies many years ago, but they seem to no longer exist.

Next - any hints on what would be good starting positions for the low & high-end needles ? I've been away from these engines for so long that I don't remember any of their typical settings.

Thanks in advance for any help you guys can provide.

In case of different carb models etc making a difference, perhaps these pics help...

Gordon

Gordon,


The MVVS .40/6.5 GFS/R is still in production by MVVS in Brno CZ.
The #3248 tuned silencer and the #3216 carburettor and parts, are too and are available for sale, by dealers outside the USA.

Morris Hobbies is no longer dealing for MVVS (since over three years ago).

The carburettor on your engine is an old version and the new carburettor is quite inexpensive.
I would strongly suggest replacement to the new version of the same carburettor, over replacing parts of the old one and leaving its rich mid-range...

The new carburettor has an elaborate intake 'trumpet, no stop-screw and a tapered-tip on the low-speed needle.


It is very linear in response, has excellent suction; even if the larger 8 mm #3219 version is used, the parts are of much better tolerance (0 ?) and obviously, everything is brand new.

See photos.
