Hi Paul, I did get lucky with the ad I must admit. The chap had it up for £245 on an auction and no one placed a bid! I missed it at the last minute and so messaged him offering £200 to collect and to my surprise he said yes! That's interesting that you have a 28 carb as the inlet on my engine measures around 35mm. Maybe I need to purchase another inlet if mine isn't stock.

@MIGHTYMAN my inlet was damaged so I thought that's ok I'll fit a dt one, the dt manifold was to small for the dellorto carb so I enlarged derestricted and flowed it with the help of my trusty pen knife and a Dremel with a flap wheel on it.

I'm definitely considering just getting a stock DT carb and inlet as a Dell Orto is proving too hard / pricey to source.
@MIGHTYMAN I found a dellorto phbh 28 for about £60 new, they use them a lot on vespas. I was thinking about using one on my 180 gilera runner fxr but I'm trying to keep it standard.

@tdrpaul The stock carb is better than those PHBH Carbs. They are a 28mm round slide carb. Flat slide is far superior.
@Calum hi Calum I agree the flat slide is a lot better carb but the dellorto phbh 28 is the standard carb for the early Italian made tdr 125.
I have a low mileage one owner 1989 tdr and I want to keep it totally original but finding original parts isn't easy.Paul

@MIGHTYMAN or grab a mikuni tmx 32. They are common enough.
-
@Calum Would I then still need a stock DT inlet for a tmx 32? Or is there a chance my current BIG inlet would be alright?
@MIGHTYMAN the manifold in the pic is the standard manifold for the dellorto carb which has the oil pipe connection on the carb.

@MIGHTYMAN Stock carb is 28mm TMX 32 is 32MM. So it should fit,.

Now it's (hopefully) going to be warming up outside a bit, I thought I would get back into this project again. Last night took a look at the crankshaft to find some of the bits of piston had been lodged inside the gaps in the conrod..
Also started the clean up job on the engine cases.
